What is Engine Start-Stop Technology and How to Use It?
2 Answers
Engine start-stop technology refers to a system that automatically shuts off the engine when the vehicle comes to a temporary stop during driving (such as waiting at a red light). When it's time to move forward again, the system automatically restarts the engine. More information about vehicle start-stop systems is as follows: 1. How the start-stop system works: When the vehicle stops moving due to traffic congestion or at an intersection. The driver presses the brake pedal and shifts to neutral. 2. The Start/Stop system automatically checks: The engine is idling and not in gear; The wheel speed sensors of the anti-lock system show zero rotation; The electronic battery sensor indicates there's sufficient energy for the next start. After these three conditions are met, the engine automatically stops running.
My car has this feature, and I've been using it for almost two years now. It's quite convenient. The engine start-stop technology automatically shuts off the engine when you stop at a red light or in traffic, and it restarts when you press the accelerator to move again, which helps save fuel and reduce emissions. How to use it? Basically, in most cars, it's automatically enabled once you start the engine. If you brake steadily and come to a complete stop, the engine will shut off after a few seconds. When the light turns green and you press the accelerator, it starts up again on its own, without you needing to press any buttons. I find it especially useful when driving in the city with lots of red lights—it saves me a lot on fuel costs over a year. However, you need to make sure your battery is the AGM or EFB type specifically designed for start-stop systems, as regular batteries can wear out quickly. Also, in summer, the frequent restarts when the AC is on can be a bit annoying, but you get used to it.
